how can i check the shortcut (default) ? e.g. [browser : www] does not work but [browser : firefox] does ; btw why have i 2 versions : firefox & firefox-esr ? & crtl+alt+t does not start the terminal but [run command prompt : alt+f2] works.
- do you know a command or a soft doing the job just for testing the validity of these debian settings (default) ?
